Description

  The present invention relates to a reciprocating mechanism, and more particularly to a reciprocating mechanism for a spinning reel that reciprocates back and forth in conjunction with the rotation of a handle, with a spool shaft that is mounted on a reel body movably back and forth and a spool is mounted at the tip.

  The spinning reel is provided with an oscillating mechanism for evenly winding the fishing line around the spool. As the oscillating mechanism, there are known a reduction gear type having a cam gear meshing with a master gear and a traverse cam type having a screw shaft rotating in conjunction with a pinion gear.

  A traverse cam type oscillating mechanism has a screw shaft arranged in parallel with a spool shaft to which a spool is fixed, an interlocking mechanism for rotating the screw shaft, and a sliding member engaged with the screw shaft. ing. A female thread portion is formed at the rear end of the spool shaft, and the sliding member is fastened to the spool shaft by screwing a bolt into the female thread portion. Therefore, when the sliding member reciprocates back and forth along the screw shaft, the spool shaft also reciprocates similarly.

  In such an oscillating mechanism, the sliding member has a main body member and an engaging member housed in the main body member. A spiral groove is formed on the outer periphery of the screw shaft, and an engagement portion on the distal end side of the engagement member is engaged with the spiral groove. The main body member has a through hole (mounting hole) penetrating in a direction intersecting the screw shaft, and a shaft portion on the proximal end side of the engaging member is slidably inserted into the through hole. At the tip of the through hole of the main body member, a retaining portion (small-diameter flange) having a smaller diameter than the other portion is formed, and the diameter between the engaging portion and the shaft portion of the engaging member is larger than that of the retaining portion. The contact portion (the flange portion) is formed, and the contact portion of the engagement member is brought into contact with the retaining portion of the main body member, thereby restricting the engagement member from moving in the screw shaft direction (for example, , See Patent Document 1).

JP-A-10-108599

  In the conventional oscillating mechanism, the engagement member is restricted from moving in the screw shaft direction by bringing the contact portion of the engagement member into contact with the retaining portion of the main body member. Further, here, in order to downsize the entire reel, in particular, in order to reduce the lateral width of the reel, a part of the main body member is cut and the screw shaft is offset to a position where it overlaps with a part of the main body member. Conceivable. At this time, since the body member is formed with a notch having an arc-shaped side cross section from the tip of the through hole toward a part of the retaining portion, in particular, the thickness of the retaining portion (the transverse direction intersecting the screw shaft) In some cases, a portion formed with a very small thickness) appears. Thus, when the thickness of a part of the retaining portion is formed thin, there is a possibility that the strength of the retaining portion is insufficient. Therefore, in order to solve such a problem, the retaining portion is provided with an annular portion formed on the inner peripheral portion of the through hole so as to project annularly on the inner peripheral side, and an inner peripheral portion on the inner peripheral portion of the annular portion. It is conceivable to have a pair of projecting portions formed so as to project in a circular arc shape with an interval so as to face each other. Here, since the contact portion can be brought into contact with the annular portion and the pair of projecting portions, the strength of the retaining portion can be increased. However, when a pair of protrusions formed so as to protrude in an arc shape is provided in this way, particularly when the main body member is formed by a molding process such as casting, the arc-shaped protrusion has a very poor flow of hot water. Therefore, it is difficult to process the retaining portion with high accuracy.

  An object of the present invention is to maintain the strength of a retaining portion in a spinning reel reciprocating mechanism and to process the retaining portion with high accuracy.

  A reciprocating mechanism according to a first aspect of the present invention is a spinning reel reciprocating mechanism that is mounted on a reel body so as to be movable back and forth, and reciprocates back and forth in conjunction with rotation of a handle on a spool shaft having a spool mounted on the tip. And a screw shaft and a slider. The screw shaft is disposed along the front-rear direction on the reel body, has a spiral groove that intersects the outer peripheral surface, and rotates in conjunction with the rotation of the handle. The slider has a main body member and an engaging member, and reciprocates in the front-rear direction by rotation of the screw shaft. The main body member is coupled so that the spool shaft is at least unable to move back and forth. One end of the engaging member is attached to the main body member, and the other end is engaged with the spiral groove. The main body member has a through hole and a retaining portion. The through hole is formed along a direction intersecting the spool shaft direction, and the engaging member is mounted from one end side to the other end side. The retaining portion restricts the engagement member from moving in the screw shaft direction when a part of the engagement member comes into contact with the inner circumferential portion on the other end side of the through hole and protrudes toward the inner circumferential side. The engaging member has a shaft portion, an engaging portion, and a contact portion. The shaft portion is supported by the inner peripheral portion on one end side of the through hole. The engaging portion is provided on the other end side of the shaft portion, protrudes in the screw shaft direction from the opening on the other end side of the through hole, and engages with the spiral groove. The contact portion is provided between the shaft portion and the engagement portion so as to have a diameter larger than the minimum outer diameter of the engagement portion, and when the shaft portion and the engagement portion are attached to the through hole from one end side to the other end side. An annular portion that contacts the retaining portion. The retaining portion has an annular portion and an ear portion. The annular portion is a portion that is formed so as to project annularly toward the inner peripheral side on the inner peripheral portion on the other end side of the through hole, and at least a part of the contact portion can be contacted. The pair of ears protrudes at least in a virtual arc portion of a virtual arc portion formed by virtually projecting in an arc shape with an interval so as to be opposed to each other on the inner circumference side of the annular portion. The part including the part is formed as a remaining part virtually cut out, and at least a part of the contact part is a contactable part.

  In this reciprocating mechanism, the retaining portion is formed on the inner peripheral portion of the through hole so as to project annularly on the inner peripheral side, and the contact portion can contact with the annular portion, and the inner peripheral portion on the inner peripheral portion of the annular portion. Of the virtual arc portion formed so as to virtually protrude in an arc shape with an interval so as to face each other, and is formed as a remaining portion obtained by virtually cutting away the portion including at least the maximum protrusion portion of the virtual arc. And a pair of ears that can be contacted with each other. In particular, the pair of ear portions is formed as a remaining portion obtained by virtually cutting out a portion including at least the maximum projecting portion of the virtual arc of the virtual arc portion formed so as to virtually project in an arc shape. For this reason, a part equivalent to the conventional arc-shaped protrusion part is not formed in a pair of ear part. Therefore, even when the main body member is formed by a molding process such as casting, since the portions where the hot water flow is poor are not formed in advance in the pair of ear portions, the retaining portion can be processed with high accuracy. In addition, since the contact portion can be brought into contact with the annular portion and the pair of ear portions, the seating surface of the retaining portion can be reliably secured and the strength of the retaining portion can be increased. Therefore, with the above configuration, the retaining portion can be processed with high accuracy while maintaining the strength of the retaining portion high.

  A reciprocating mechanism according to a second aspect is the reciprocating mechanism according to the first aspect, wherein the screw shaft is disposed at a position where at least a part thereof overlaps the main body member. The main body member is cut so that a cross section in the spool axial direction is a substantially arc shape surrounding the outer shape of the screw shaft so that the screw shaft does not contact, and at least a part of the retaining portion on the other end side of the through hole is cut off. It further has a notch cut out in the spool axial direction. In this case, by cutting a part of the main body member into a substantially arc shape and offsetting the screw shaft to a position where it overlaps with a part of the main body member, the lateral width of the reel can be reduced and the entire reel can be reduced in size. In particular, in this case, the main body member is formed with a notch having a circular cross-section in the side section from the tip of the through hole toward a part of the retaining portion. Even if a portion appears, the contact portion can be brought into contact with the annular portion and the pair of ear portions, so that the strength of the retaining portion can be increased.

  The reciprocating mechanism according to a third aspect of the present invention is the reciprocating mechanism of the first or second aspect, wherein the ear portion is formed such that the outer shape of the cross section of the maximum projecting portion is an arc shape. In this case, since the ear portion protrudes so as to have a substantially 8-character shape, the seating surface of the retaining portion can be reliably secured.

  The reciprocating mechanism according to a fourth aspect of the present invention is the reciprocating mechanism of the first or second aspect, wherein the ear portion is formed such that the outer shape of the cross section of the maximum protrusion is linear. In this case, since the protruding amount of the ear portion is minimized, it is possible to prevent a portion having a poor hot water flow from being formed in advance.

  A reciprocating mechanism according to a fifth aspect of the present invention is the reciprocating mechanism according to any one of the first to fourth aspects, wherein the ear portion has a groove portion that is recessed from the maximum protruding portion toward the inner peripheral portion of the through hole. . In this case, in particular, when a part of the main body member is cut into a substantially arc shape and the screw shaft is offset to a position where it overlaps with a part of the main body member, a portion where the thickness of the ear portion is formed very thin appears. However, by forming the groove portion in the ear portion, a portion where the ear portion is formed very thin is not formed, so that a portion where the hot water flow is bad can be prevented from being formed in advance.

  A reciprocating mechanism according to a sixth aspect of the present invention is the reciprocating mechanism according to any one of the first to fifth aspects, further comprising a plate-like member fixed to the main body member with a screw member so as to close the opening on one end side of the through hole. ing. In this case, the engagement member can be prevented from coming off by providing the plate-like member.

  A reciprocating mechanism according to a seventh aspect of the present invention is the reciprocating mechanism according to any one of the first to sixth aspects, wherein the first guide shaft and the second guide shaft that are disposed along the front-rear direction of the reel body and guide the slider in the front-rear direction are provided. It has more. In this case, providing the first guide shaft and the second guide shaft ensures the guide of the sliding member.

  According to the present invention, in the reciprocating mechanism of the spinning reel, the retaining portion is formed on the inner peripheral portion of the through-hole so as to project annularly toward the inner peripheral side, and the annular portion that can contact the contact portion, and the annular portion A virtual arc portion formed by virtually projecting in an arc shape with an interval so as to face each other on the inner circumference side of the inner circumference portion of the imaginary portion of the virtual arc portion at least including the maximum projection portion of the virtual arc is virtually cut off Since it has a pair of ear | edge part which can be contacted by the contact part formed as the remaining part, while maintaining the intensity | strength of a retaining part high, a retaining part can be processed with high precision.
